A method to measure the emissive concentration of 5-ethylidene-2-norbornene (ENB), a reactive compound used in industrial synthesis of terpolymers, has been developed. The starting points for the development of the presented method are European and Italian reference methods for the

The acute toxicity and primary irritancy of the industrial chemicals 5-ethylidene-2-norbornene (ENB) and 5-vinyl-2-norbornene (VNB) were studied. They are of moderate acute peroral toxicity in the rat, with LD50 values for ENB of 2.54 (male) and 5.66 (female) ml kg(-1)

Several predictive models were used to assess aquatic exposure, persistence (P) and potential for long-range transport (LRT) of 5-ethylidene-2-norbornene (ENB). Such estimations are components of the assessment process for persistent, bioaccumulative and toxic (PBT) substances, which are also referred to

5-Ethylidene-2-norbornene (ENB) is an industrial chemical whose physical properties indicate a likelihood for vapor exposure to humans. The potential for target organ or cumulative toxicity was investigated in rats exposed for 6 h per day for 9 days over an
